The rod formsone part of a feed mechanism or a device for moving the Iile into thespaces between the various teeth of thesaw to be operated upon. Theother portions of the -feed mechanism will be described in the order ofassembling the parts.

A hanger 19 is provided having a vertical portion upon which is formedan interiorly screw-threaded sleeve 20, to receive the threaded portionof the rod 16. The lower end portion of the hanger terminates in aslide.21 having an inverted triangular aperture which is adapted toreceive a correspondingly shaped bar 22, the opposite ends of which aremounted in lateral sockets formed in the ends 7 and 8. The bar 22 isheld against displacement by means of set screws 23 screwed into theends 7 and 8 to bind on the-op osite ends of the bar22. The surfaces oft e bar 22 are provided with a plurality of graduations or scale marks24, the spaces between the markings on each of the surfaces beingdifferent in width to conform to the pitch of different saws and two ofsaid bars are furnished with each machine one having an even number ofgradua ,tions and the other having an odd number so that saws having aneven or an odd number of teeth to the inch may be filed properly.Depending from the medial portionof the lower end of the slide 21 is ashaft 25.

The file holder and the means for connecting the same to the shaft.25will now be described.

A vertical sleeve member is designated by the numeral 26 and is of asize to loosely receive the shaft 25. This sleeve member is providedwith a lateral screw threaded opening for the reception of a set-screw27 to bind on the shaft 25. Formed on the exterior of the sleeve 26diametrically opposite to the opening for the set-screw, and eX- tendingat the right axis of the sleeve is a sleeve 28. By reference now to thedrawings it will be seen that the shaft'25 is provided with a pluralityof spaced vertical lines 29, and further provided with a plurality ofspaced horizontallines 30crossing the lines 29, and depending from thelower end of the sleeve 26 is a pointer 3l adapted to work over saidgraduations. Secured to the vlower side portion of one end of thehorizontal sleeve 28 ips a sector-shaped plate 32 having on its outersurface a plurality of graduations 33 and the horizontally dis-v posedsleeve 28 has a pin 34 mounted therein, one end of which extends throughone end of the sleeve and is provided with a depending inger 35,overlying the graduated surface of the sector-shaped plate 32. `'Theopposite end of the pin 34 is providecf'with a sleeve-3G. The sleeve 28has a setiI screw therein adapted to lock the pin 34 aigainst rotation.The sleeve 36 loosely receives a rod 37, forming the body portion of acomopposite ends of the body being provided with handle grips 42. Theopening in the smaller block 38 is of a size to nicely receive the body41, while the oblong opening is considerably greater in length than thewidth of the block, as clearly shown in the.

drawings.

Th file is designated by the numeral 43 and. is positioned on the medialportion of the lower sidey of the body 41, one end of the file extendinginto a socketed block 44, and its opposite end being received by arecess 45.

Slidingly tit-ted on the body 41 of the file holder is a collar46, whichslides over the recess 45 and has formed in the side adjaf cent to therecess an opening to receive a set-screw 47, adaptedto Abind. on thefile when positioned in the recess to prevent end wise and lateralvmovement of the le.

In the operation of the deviceand assuming that a sawA is positionedbetween the sections of the lower side in a manner be fore described andthevvertical sleeve 26 is positioned on the shaft 25the, set-screw inthe sleeve is moved from engagement with the shaft, thus permit-ting thefile holder and its parts .to descend so that t-heffile will enter the'space between two adjacent teeth of the saw. Assuming that the teeth areto be sharpened the file holder is turned until one face of the tilebears on the beveled side of the teeth, after whichI the vertical sleeveis locked againstmovement by turning the set-screw 27 thereof intoengagement with Athe shaft 25. It will be seen when the parts are sopositioned the body portion of the file holder may be reciprocated inthe ordinary manner and after the tooth has been filed the said' bodyportion may be moved upwardly in the oblong opening in the block and thehand wheel turned until the file is in the position to enter the nextsuccecding space between the teeth. By reference now to the drawings itwill be seen that a gage screw 48 is threaded into the lower end of theshaft 25. When the filing of the saw has proceeded far enough in eitherdirection it is necessary to move the saw so that the tiling may becompleted to either end. The screw runs down on the teeth, the clampscrew loosened, and the saw moved so as to enable the operator to fileall teeth clean to the end. rlhe saw is then pushed up in the frameuntil the teeth engage the screw and clamping screw fas# rier,- :is willhe clearly understood W' hen the lower end et 'the oblong opening L0vmoves below the lower side of ,the body 4:1

of* the ile carrier, (the tile carrier resting upon the saw), the sleeve2G 1s secured to the shaft in themnnner before described and the fileholder then reelprocated in the.usual manner. The file will then eutinto the sljanv` blade untilthe lower side of the file holder hears onthe lower-end of the opening 40, whereby further downward movement ofthe tile ,will he' prevented. l

From `the foregoing, it is evident that I have provided e device ivhichis compara'- tively simple in structure and inexpensive to mnnutacture,embodyingfew parts and these Fo arranged that the' danger ofderzingementwill he reduced to n minimum.
